Looking for some advice about ayahuasca and mushrooms

[AlchemyAlice]

Hi guys, I've got the chance to go and sit with aya on the 6th august, it's with the huni kuin tribe pretty close to my home so not an opportunity that comes up often.. my friends have arranged a night out for my birthday 8 days before so obviously I couldn't drink if I was going to ceremony but wondering if I could take a small dose (1/1.5 of mushrooms?) I've taken mushrooms after ceremonies a few times and feel they helped unpack and integrate the experience but not sure about a week before and can't find much on the internet. Thanks for any input?
